Tech Tips


  • When any of the speed sensors or the yaw rate sensor assembly has trouble, DTCs for the steering sensor may be stored even when the steering sensor is normal. When DTCs for the speed sensors or yaw rate sensor assembly are output together with DTCs for the steering sensor, inspect and repair the speed sensor and yaw rate sensor assembly first, and then inspect and repair the steering sensor.
